When was the last time you rode in an electric vehicle almost entirely constructed of carbon fiber and good for 250 miles on a charge? We're laying odds on "never," which is why we turned a shade of violent green when we saw Fully Charged host (and part-time Series 4000 Mechanoid) Robert Llewellyn set foot in just such a car. Delta Motorsport's E4 Coupe, originally designed to win an Automotive X-Prize, is the vehicle we're referring to here, and despite the fact that only one-third of its full projected power was available to coax Mr. Llewellyn firmly into his racing seat (four-wheel drive and regenerative braking are also TBD) and set his teeth on edge, we have to give the man some major props for documenting the experience for us on film. Watch it after the break.
